To all whom may concern:

Be it known that l, BERNIE C, KiuDLnn, a citizen of the United States ot America, and a .resident ci Flint, in the county of Genesee and State of Michigan, have invented certain new and uselul improvements in a Roofing Shingle, of which the following is a specification.

Among the principal objects which the present invention has in view are: To construct roof covering of shingles without the aid ot fastening devices driven therethrough; to reduce the time factor required for installing the shingles in serviceV relation; to improve the alignment oi shingles when installed in service; to avoid splitting the shingles used for root covering; and to secure the saine in service relation.

Dra/wings.

Figure 1 is a sectional view showing the service relation of shingles when disposed in root coverin and constructed and arranged in accor ance with the present invention.

Figure 2 is a top view of a shingle constructed and arranged in accordance with the present invention.

Figure 3 is a side edge view of the saine.

Figure d is an end edge view of the saine.

Figure 5 is a bottom view ot the same on reduced scale.

Figure 6 is an edge view ci shingles constructed in accordance with the modied forni ot the invention.

Figure 7 is a side edge view of the shingle the lock member being constructed in accordance with a further modification of the invention.

Figure 8 shows a diderent modiication of the retaining lug of the shingleaconstructed in accordance with the present invention.

or other metallic driv-l hammer or when the shingle has been constructed of brittle or fragile material by breaking the saine with punching instruments used in connection therewith. Another objection which has been found has resided in the tact that the shingles have been o ften cracked lengthwise, the fracture not being at the time observed and only dis covered when lrost or ice has entered the fracture and spread the same, convertin it from a somewhat innocent, to a vicious ealr in the root coverin 'lhe principal obgect of the present invention is to overcome these defects. .lo that end each shingle is provided with one or more holding lugs 16. The lugs 16 are preferably disposed adjacent the edge of the shingle and spaced apart to provide a channel 17 therebetween. rllhe lugs 16 as may be seen best in Figures 2 and 5 are aligned in transverse relation to the shingle and are adapted :tor engagement by a straight furring strip or narrow sheathing board 18.

'llhe sheathing boards 18 are forced down on the lugs 16 before driving the screws 19 or other fastening devices into the rafters 20 or the roof structure.

When using shingles constructed and arranged in accordance with the present invention the rafters 20 are preliminarily provided with a course board 21 secured to the rafters at the ends thereof to form the eaves oi the root. Before laying the lirst course of shingles 15, a iurrin strip 22 is secured to the course board 21 adjacent the lower erposed edge thereof. rlhe strip 22 is engaged to support the tree end ot the shingle 15 when the lower edges of the lugs 16 rest on the rafters 20 as shown. Should the lugs fall between the rafters, then the shingles will be supported by the superposed sheathing board 18. rllhe rst sheathing board 18 is then introduced and disposed behind or above the lugs 16 on the rst course of shingies. While the sheathing board 18 is held firmly in place, the screws 19 are driven home. The boards 18 are equal in width and constitute ages for setting the various courses of tiles that is to say, the width oit the board 18 plus the length of the lugs 16 equals the exposed surface of each course o tiles,

lll@

The second course of tiles is than disposed so that the lugs 16 thereof rest on the sheathn ing board 18, which has just been disposed in. place, the skirt of the second course of shingles overhanging the butts of the first course of shingles. The usual practice of staggering the joints between shingles is pursued when covering a roof with shingles herein described.

The shingles are thus laid, course by course, the sheathing boards being permanently secured to the rafters 20 as the coverin approaches the ridge ofthe roof.

W ile I prefer the straightsided lugs 16 as shown in Figures 1 to 5, inclusive, it will be understood that if greater security in the lock is desired, lugs having ends shaped as shown in Figures 6 7 and 8 may be employed. Whenever lugs of this character are employed, it will be recognized that the edges of the sheathing boards 18 will conform with the recesses 16', 16" or 16 of the lugs formed in the modiications.

Claim.

of said body and adapted to snugly lit be- ,necesa tween the opposed edges of said sheathing strips. 3. In combination, a roof structme including eguidistantly spaced straight edged sheathing strips each of an even thickness and a shingle comprising a tapered body, an 1u space d apart transversely of the under si e of said body and adapted to snugl fit between the opposed edges of said sheathing strips. l 4. In combination, a roof structure including eguidistantly spaced straight edged sheathin strips, and a shingle comprising a tapered od and lugs spaced a art transversely of t e under side of sai body and adapted to snugly lit between the opposed edges of said sheathing strips, said lu s being ro'oved to admit of the free circu ation of air beneath the shingle and to otherwise reduce the weight of the same without materially decreasing the strength thereof.

5. In a roof structure, straight edged sheathing strips spaced equidistantly apart.

one parallel to the other, shingles adapted to belaid on said sheathing strips, said shingles being tapered whereby to flatly contact one in overlapping relation with the other, and a lug formed on the under sides of said shingles and adapted to snugly fit between the opposed edges of adjacent sheathing strips, the width of the sheathing strip engaging the upper side of a lug combined with the length of the lug itself approximating the length of the exposed surface of a shingle whereby to uniformly gage the shingles laid 1n successive rows on the roof structure.
